Interesting theory on exercise fatigue

A while back, I read an article in a magazine about Jure Robic, an ultracyclist who has won 3 Race Across America titles, and holds multiple records for endurance cycling. I remember him quoted in the article as saying something like, 'I know when I am in pain and beyond fatigue and feel that I need to quit, that I have only used 30% of my physical capacity. I tell myself I still have 70% to go, and I keep going." This fellow is known for extremity in his training, and yet, he is physiologically rather un-extraordinary, as determined by laboratory testing.

I got curious about this, and started to surf online for any science to back this up, and I found a series of articles written by South African scientists named Noakes and Lambert. (A google search will yield dozens of citations.)

They theorize that muscle pain and fatigue are NOT solely due to glycogen depletion or lactic acid buildup, or any local event in the muscle. They say it's a cognitive-emotional brain response designed as a feedback loop to get us to slow down, stop, or rest, but that we are indeed, nowhere near "out of gas" when we think we are. It's a dance between the chemistry of hard-working muscle, and the mind.

They observed, for instance, that exercise fatigue is diminished more so under hypnosis, a central event, than while drug-enhanced, a peripheral event.

It surely makes a case for paying attention to training the mind as well as the body. I have a bag of mental tricks I pull out when I think I can't go anymore. One of them is that I think about Jure Robic!

Re: Interesting theory on exercise fatigue

Sure mind over matter has a very powerful impact on one's physical limitations. Reminds me of Rocky (more heart and determination) beating the Russion powerhouse (who was much stronger, fitter and more skilled.

What the mind percieves the body achieves. Its mental toughness that is usually the determining factor between the professional athletes and the semi pro guys.

Why are so many people obsessed with Rocky? He is a fictional character, after all.

Because of what he represents. And I don't mean Philly.

Dude,

Rocky is inspirational - they show it to people with depression and it lifts them up.

If something inspires you on towards greatness what's the issue? I love My Name is Earl for the simple fact that he does good things.
